bay gio mk ranh rui mk lam cho

x+5.2-(32+16.3:6-15)=0

x+5.2-(32+48:6-15)   =0

x+5.2-(32+6-15)        =0

x+5.2-(38-15)            =0

x+5.2-23                   =0

x+10-23                    =0

x+10                         =0+23

x+10                         =23

                              x=23-10

                              x=13

chuc bn hoc gioi!

x+5.2-(32+16:3x6-15)=0

=> x+ 5+10-(32:32-15)=0

=> x+ 15- (-14)=0

=>x+15 +14=0

=> x= 0-14-15

=>x= -29

dài quá ko làm nha!!!

25 nhé bạn

ý lộn 15 nhé bạn

2X.(32+16.13:16-15)-5.2^3=0

(=)2X.(32+13-15)-5.8=0

(=) 2X.30-40=0

(=) 2X.30=40

(=) 2X=10

(=) X=5

Thiếu rồi!Không được làm tắt.

a)\(\left(x-140\right)\)\(\div\)7=27-4-3 =20\(\Rightarrow\)    \(\left(x-140\right)\) =20x7=140\(\Rightarrow\) x=0
